Watering, pruning, propagation, and repotting details from plant data
Allow the soil to dry out completely between waterings. During the growing season (spring and summer), water thoroughly when the top inch of soil is dry.
Reduce watering significantly in fall and winter, providing only enough to prevent complete desiccation.
Pruning is generally not required for Arthrocereus rondonianus, as it maintains a desirable natural shape. If removal of damaged or dead stems is necessary, use a clean, sharp knife or shears.
Disinfect tools to prevent disease transmission.
Propagate by stem cuttings. Allow cuttings to callus over for a few days to a week before planting in a well-draining cactus mix. Keep slightly moist and in bright, indirect light until roots form.
Repot every 2-3 years or when the plant outgrows its container. Use a fast-draining cactus or succulent potting mix. Choose a pot that is only slightly larger than the current one, with drainage holes.
Repot in spring before the active growing season.
